The positioning mechanism (200) and the riveting mechanism (300) are respectively inclined at the same angle as the slide groove (211).

4. The stent twist riveting apparatus of claim 3, wherein: The base mechanism (400) includes a base plate (410), one end of which is connected to the base via an adjustment mechanism, and the other end of which is rotatably connected to the base away from the adjustment mechanism. The adjustment mechanism can drive the base plate (410) to rotate.

5. The stent twist-riveting apparatus of claim 1, wherein: The torsion member (326) is provided with a bayonet, and the propulsion mechanism pushes the torsion member (326) to put the bayonet on the rivet (2) of the product bracket (1).

6. The stent twist riveting apparatus of claim 5, wherein: The rotating mechanism includes a gear (323) coaxially disposed on the outside of the torsion member (326) and a rack (322) connected to the first transverse cylinder (312). The rack (322) meshes with one side of the gear (323). When the first transverse cylinder (312) drives the rack (322) to move along the length direction, the gear (323) drives the torsion member (326) to rotate.

7. The stent twist-riveting apparatus of claim 5, wherein: The positioning plate (321) is connected with the pushing mechanism, and the positioning plate (321) is provided with a avoiding hole for avoiding the torsion member (326), the pushing mechanism can push the positioning plate (321) to press against the side of the product support (1), and the torsion member (326) is sleeved on the rivet (2) of the product support (1) through the avoiding hole.

8. The stent twist-riveting apparatus of claim 5, wherein: The rotating mechanism is arranged on the torsion riveting frame (320), the pushing mechanism comprises a second horizontal moving cylinder (340), the torsion riveting frame (320) is connected with the second horizontal moving cylinder (340) through a rotating torsion riveting push rod (313), and the torsion riveting frame (320) is provided with a torsion riveting adjusting screw (331).

9. The stent twist-riveting apparatus of claim 1, wherein: The control system (500) comprises a plurality of electromagnetic valves (535) and a plurality of magnetic switches connected with a PLC controller (520) respectively, the plurality of electromagnetic valves (535) are used for controlling the feeding mechanism (100), the positioning mechanism (200) and the torsion riveting mechanism (300) respectively, the plurality of electromagnetic valves (535) and the plurality of magnetic switches are one-to-one corresponding, and the PLC controller (520) can open the electromagnetic valves (535) and close the electromagnetic valves (535) when the corresponding magnetic switches of the electromagnetic valves (535) act.

10. The stent twist-riveting apparatus of claim 1, wherein: The control system (500) comprises an electric control box (510), and a PLC controller (520), a leakage protector (521), a switching power supply (522), a three-way joint (530), an air pipe (531), a hand slide valve (532), a busbar (533), a silencer (534) and an electromagnetic valve (535) are installed on the electric control box (510) respectively.
